Hm ... well, you do get some other high quality cans once you get closer to $150 and $160, I could find some recs in that area as well.
The CAL!, like I said, was my first foray into quality headphones and I still use them to this day (I'm using them now), even though I own pairs that are superior. Thing about those are is the cord is relatively short, so if you're out and about that might be an issue. You might need an extension.
The 580 are excellent headphones. Objectively, they've got a better sound than the CAL!, but it is a different one. There's more bass, a very VERY detailed bass, with somewhat recessed vocals .. as in they're not at the forefront, but they do have a great sound and they're worth spending a bit more. Not quite as comfortable, but a longer cord. The pleather pads they come with are really stiff out of the box but they loosen up.
Here's another one that's a bit more expensive that is one of the most recommended headphones out there, the Audio Technica ATH-M50. http://www.amazon.com/Audio-Technica-ATH-M50-Professional-Monitor-Headphones/dp/B000ULAP4U?tag=duckduckgo-d-20
As far as wanting style, there's nothing wrong with that. You're making an informed decision and style is just one of the factors, as it should be. For instance, take a look at these - the Sennheiser HD800. Widely considered to be one of the top headphones in the world ... I'd NEVER buy them. I think they look HIDEOUS. If they were objectively THE BEST, then I might consider it, but if there's options that are similar + look better, then ... hey, that's perfect.
